How to find out details about hardware on the Linux machine?
Solution 1:
lspci for pci cards, lsusb for usb, lshw works on debian based distros, here's a list of ways to get other hardware specs,
Solution 2:
If available, dmidecode comes in handy. Particularly on Dell, HP, IBM hardware, where they bother to program relevant hardware information into the various registers.
Solution 3:
lspci is a great utility for listing the system hardware. (Anything on the PCI bus, anyway.)
cat /proc/cpuinfo - Displays CPU info
cat /proc/meminfo - Displays memory info
dmesg (or cat /var/log/dmesg) contains some info, not necessarily everything.
If you have a RedHat/CentOS system, you can use sosreport to collect a good bit of information, though I don't know if it has all the hardware info listed in it.
Those are some good places to start to find the info you're looking for.
Solution 4:
The /proc filesystem will give you the information that you want... BUT i don't know how you will get it is one easy place.
'cat /proc/cpuinfo' will tell you about your CPU 'cat /proc/devices' will tell you some limited information about block devices. 'ifconfig -a' will tell you about network connections
Others will be able to tell you about more devices. Are you troubleshooting a particular device? If so, you will get better help asking a specific question.
Solution 5:
inxi will show just about everything, run with no arguments for short form, the options are many however, run inxi -h to see them
inxi is a 'full featured information script' as described by the project home page: https://github.com/smxi/inxi
Here is information about how you can install it on Ubuntu: https://askubuntu.com/questions/284635/inxi-installation-on-ubuntu
